ABSTRACT:
The invention relates to method for overmolding a painted silicone prosthesis of a human extremity. A silicone prosthesis is first molded from a solid replica of a human extremity and then painted to closely resemble the color of the recipient person. An elasotmeric polymer material having the properties of elasticity, transparency, and non-adhesiveness to cured silicone rubber is applied to the replica to form a transparent glove-like overmold. The glove has an inner surface that is mirrored by the surface of the replica. The distal portion of the glove-like overmold is partially filled with a predetermined amount of viscous uncured silicone liquid and the painted silicone prosthesis is then inserted into the glove which is stretched tightly over the prosthesis. A compressive force is externally applied in a radial compressive and proximate direction to uniformly distribute the liquid silicone over the painted surface of the prosthesis. The silicone is allowed to cure and bonds to the surface of the prosthesis but does not adhere to the transparent glove-like overmold.
